3550.0. "Urgent ! pls help, DECNIS 500<--X.25-->Nokia DX200" by HGOM11::LKLEE () Tue Feb 18 1997 23:07

Hello,

I need to setup connection between our UNIX system and  Nokia DX200 switch
using  x.25 protocol in China.  Since the Nokia people here is not experience 
in this kind of connection, can anyone share some of your experience with me ?

The Nokia switch will use x.25 protocol communicate with Digital UNIX
thru decnis 500 as shown in the below diag.  Our side is configured as
DCE mode, Nokia side is configured as DTE mode.  A pair of modem is 
placed between these two systems for electrical isolation.

    FTAM is used for transfering files between unix and nokia system.


    
My current problem is the X.25 can not up and running.

I think the problem is unmatched network profile.  Please advise which network
profile should be used for communication with Nokia DX200 switch.  The Nokia
people can't find out which profile should be used.  The following is the 
parameter list  given by the Nokia people :
